I wrote my own program to draw SVG maps directly from GIS data. Anyone is welcome to try it, if you're not scared by the biggest, hairiest command-line syntax you ever saw. It is written in Perl and runs on Linux. It might work on Windows if all the required packages will load into your Perl environment there; I've never tried it.
